How to detect color from PDF java

Question

Is there any way, in java, to automatically detect the colors of a certain area in the PDF and either translate them to RGB or compare them to the legend and then get the color?

Do you want the color with which some text or some form in that area is originally drawn? Or do you want the color eventually being visible there? — mkl

What is the "the legend"? Also, it might help you get a good answer if you clarified why detecting the color is important. — Ryan
